The formula for specific heat capacity, C, of a substance with mass m, is C = Q /(m × ΔT). Where Q is the energy added and ΔT is the change in temperature.
The specific heat can be calculated from the amount of heat transferred into and out of a substance. The heat transfer equation provides a quantitative relationship between heat transfer, substance’s mass, specific heat, and temperature change.
To calculate specific heat, start by reading the problem carefully, then write down each known and unknown variable to get a better sense of what you're working with. Next, plug the known factors into the specific heat equation, then solve the equation as you normally would to get your answer!
Specific heat is the quantity of heat essential to raise the temperature of one gram of any substance by 1 degree Celsius. Specific Heat formula is articulated as \(\begin{array}{l}C\;=\;\frac{\Delta Q}{m\;\Delta T}\end{array} \)
Specific Heat Formula. As we discussed above the specific heat is the relation of temperature change of an object with water. Also, the formula is like this: Heat energy = (mass of the object or substance) × (specific heat) × (Change in temperature) Q = m × c × \Delta T. Or. Q = mc\Delta T.
Define heat capacity and specific heat capacity and differentiate between the two terms. Deduce which substance will have greatest temperature changed based on specific heat capacities. Calculate unknown variables based on known variables using the specific heat equation.
The quantitative relationship between heat transfer and temperature change contains all three factors: Q = mcΔT, where Q is the symbol for heat transfer, m is the mass of the substance, and ΔT is the change in temperature. The symbol c stands for specific heat and depends on the material and phase.
Use our specific heat calculator to calculate the energy required to achieve a desired temperature change using the specific heat formula.
In thermodynamics, the specific heat capacity (symbol c) of a substance is the amount of heat that must be added to one unit of mass of the substance in order to cause an increase of one unit in temperature.
The specific heat of a substance can be used to calculate the temperature change that a given substance will undergo when it is either heated or cooled. The equation that relates heat \(\left( q \right)\) to specific heat \(\left( c_p \right)\), mass \(\left( m \right)\), and temperature change \(\left( \Delta T \right)\) is shown below.
